Casting non-BEGO alloys
To automatically cast non-BEGO alloys, programs
must be created for them and the relevant values
determined. This is explained on the following page.
Automatic casting is only possible with Nautilus
®
CC plus.
Own programs can also be created for the manual
casting of non-BEGO alloys. This is necessary for
the printing of alloy names in the casting protocols,
for example. If no own programs are created, non-
BEGO alloys can be manually cast using the
following standard programs. During manual
casting, preheating and final heating must end on
their own, see chapter "Manual casting without
pyrometer" on page 36!
Standard programs
101 - Suitable for CoCr and NiCr alloys that tend
not to splash during melting.
102 - Suitable for CoCr and NiCr alloys that tend to
splash during melting.
103 - Suitable for Pd alloys.
104 - Suitable for EM alloys.
Casting titanium is not permis-
sible!
There is a risk of personal injury
and damage to the machine!
Aluminium (> 1 %) in non-precious
alloys without beryllium may produce
such strong oxides during melting that
major portions of the melt remain in
the crucible. Such alloys cannot be
cast with NAUTILUS
®
.
Alloys containing beryllium produce
strong oxides during melting, cause
substantial wear to the crucibles and
remain there in significant amounts.
Carcinogenic particles are released
when beryllium is processed!
Cast and finish only while taking
suitable protective measures!
Alloys with a high palladium content are cast
without a crucible insert as a rule. If alloy laminae
line up during heating and are therefore not
heated adequately (failure to "couple" to the
induction field), an insert can be used:
a graphite insert in the case of palladium content
less than 35%, a glassy carbon insert that reliably
prevents the inclusion of carbon in the case of
palladium content over 35%.
If the manufacturer of the alloy has different
specifications in this connection, they must be
followed.
